"superclass mismatch for class Mark (TypeError)"

I'm seeing this error when I try to do just about anything (rake tasks, run server, etc.). Seems to be the same cause as jlong/serve#86, fixed by adding psych to the Gemfile.

Could you confirm the environment you're running in? Interesting that I haven't run into that myself, but updating the Gemfile is an easy fix.

Sorry, should have given more information. It looks like this is a conflict between Psych and Faker, which probably both define Word classes with different superclasses. Requiring Psych first eliminates the error, but one or the other should probably scope their Word class, or maybe Faker should just include Psych before it defines the class. Adding Psych to the ASQ Gemfile is just a work-around.

BTW, this is on Linux (Fedora) running Ruby 2.3.3 under RVM.

... also, Faker v1.7.3 and Psych v2.2.4.
